摘要:
了解河南省学生餐的食品安全状况,为国家食品安全风险监测计划的制定提供理论依据.方法 结合河南省18个省辖市的实际情况,覆盖城市和农村包括城乡结合部,分配采样计划,采集河南省学生餐862份,并进行金黄色葡萄球菌、蜡样芽孢杆菌、单核细胞增生李斯特菌、沙门菌和致泻大肠埃希菌等致病菌的检测.结果 学生餐样品食源性致病菌的整体检出率为8.58%,其中金黄色葡萄球菌和蜡样芽胞杆菌检出率分别为3.13%和4.40%;致泻大肠埃希菌、单核细胞增生李斯特菌和沙门菌检出率较低,分别为0.70%,0.23%和0.12%.乳与乳制品、豆制品、米面制品以及盒饭中食源性致病菌污染率相对较高,分别为17.86%,12.50%,9.79%和8.79%.农村和城市学生餐中食源性致病菌检出率分别为14.29%和7.48%,差异有统计学意义(x2=6.920,P=0.009).结论 河南省学生餐存在致病菌污染隐患,应加强对高污染率食品类别学生餐的卫生监测和监管.
Abstract:
Objective To investigate the food safety status of student meals,and to provide theoretical basis for the planning of national food safety risk monitor.Methods A total of 862 food samples were collected and detected based on Food Safety Risk Monitoring Plan in Henan in 2014.The test items conclude Bacillus cereus,Staphylococcus aureus,Listeria monocytogenes,Escherichia coli and Salmonella.Results Among the 862 samples of student meals,the overall detection rate of main pathogenic bacteria was 8.58%.The detection rate of Staphylococcus aureus and Bacillus cereus were 3.13% and 4.40%,and lower detection rate was 0.70%,0.23% and 0.12% in Escherichia coli,Listeria monocytogenes and Salmonella.The detection rate of milk and dairy products,bean products,rice food and box lunches was 17.86%,12.50%,9.79% and 8.79% respectively.There were significant differences of food-borne pathogenic bacteria detection between students in city(14.29 %) and those in countryside(7.48 %) (x2 =6.920,P =0.009).Conclusion There are hidden dangers of foodborne pathogenic bacteria contamination in student meals provided by school in Henan Province.In order to avoid the break of food poisoning in school,food safety monitoring and supervision should be strengthened on high contamination rate of student meals.
